Both are a consequence of it, fear and insecurity are the worst feelings in trading, when you have a trading plan you must comply, you must follow the rules that you impose yourself, if you violate your same rules  not have discipline and will leave everything to luck or worse will gambling and the safest thing is to lose.

To avoid these feelings of panic and postpone trades, it is best to put:

1.-Stop Loss.
2.-Take Profit.

Place both in each trade, and then not look at the market, go do other things and go to the hours, 4h is the best, then see, if it was lost, it is time to assume the loss, and if it was won, well congrats.

But always follow your trading plan, and another way to avoid panic is not seeing Crypto news, because often it often influences people's decisions such news.
